CPA-RefSel: CPAchecker with Refinement Selection
Our submission to SV-COMP’16 is based on the software verification framework CPAchecker. We suggest to combine the value and predicate analysis of the framework, both performing CEGAR based on interpolation. The novelty of our approach is that both analyses perform intra-analysis refinement selection, with a top-level refinement component additionally employing inter-analysis refinement selection. All in all, this allows for an efficient verification process, as intra-analysis refinement selection selects a suitable refinement for an analysis and inter-analysis refinement selection selects the analysis that is best to be refined.
